Product Detail

Improvement of the one-time pass rate of the MCCB metal stamping mold

The accuracy of the mold should be high, mainly reflected in the improvement of the mold precision by the mold processing technology, and secondly, the accuracy of the punch also affects the accuracy of the product.

The mold worker should be professional, the mold worker's control of the mold accuracy and algorithm will also affect the one-time pass rate of the mold. The key dimensions of many precision molds are not allowed to have a slope, but the tolerance zone and a small slope will be fully used in mold manufacturing, such as gear installation column.

When building a digital model, we must pay attention to the adjustment of tolerance. Generally, the 3D model provided by customers is useless, because many of its dimensions are the limit dimensions. If we design the mold according to this, the produced mold will basically be scrapped.

Frequently Asked Questions

How can we improve the one-time pass rate of the MCCB metal stamping mold?

Improving the one-time pass rate requires high mold precision, advanced mold processing technology, stable punch accuracy, and professional mold workers who can accurately control mold algorithms and tolerance zones.

What factors affect the accuracy of the stamping mold?

Mold accuracy is primarily determined by the mold processing technology. Additionally, the accuracy of the punch machine itself plays a significant role in affecting the final dimensions and quality of the product.

Why is the expertise of the mold worker so critical?

Professional mold workers control both the mold accuracy and the mathematical algorithms during setup. Their ability to manage tolerances and apply small slopes where necessary directly impacts the success rate of the mold.

Can we design molds directly using the 3D models provided by customers?

Generally no. Customer-provided 3D models often contain limit dimensions. Designing a mold directly from these models without adjusting the tolerances can lead to the manufactured mold being scrapped.

How are slopes and tolerance zones handled in key mold dimensions?

While key dimensions of precision molds (like gear installation columns) technically do not allow slopes, mold makers must strategically utilize tolerance zones and minimal slopes during manufacturing to ensure proper functionality.
